Equalisation of Pressures There is a point at which no further brake pipe pressure reduction will result in increased braking effort, this is known as full application or equalisation of pressures.

Imagine you made a 26 psi reduction when operating a loco with a 90psi brake pipe. 90psi in the train pipe minus 26psi reduction equals 64 psi in the pipe. Due to the 2.5:1 ratio of auxiliary reservoir volume to brake cylinder volume, the 26 psi reduction puts 64 psi into the brake cylinder.

As the pressure in the reservoir and the pressure in the cylinder is now equal, no more air will flow into the brake cylinder; and making a further reduction in brake pipe pressure will have no effect on braking.

Equalisation occurs at different pressures, depending on the train pipe feed pressure.
100 psi pipe (e.g. the UK locos - 7 bar) equalisation at 71 psi.
90 psi pipe (e.g. the US locos) equalisation at 64 psi.
72 psi pipe (e.g. French & queensland locos) equalisation at 49 psi.

The easiest way to set your custom content to the desired brake pipe feed pressure is to copy the entire pressure section from the config of a loco that uses the pressure you desire.

Note: Converting PSI to Grams /m cubed...
e.g. 90psi... (90+14.7).0000703

104.7 x .0000703=.00736041
